Netstar go cancelation

Hi there, i have been trying to cancel this netstar go since january this year. I call in and the guy i spoke to said yes its been canceled, but will still deduct its last installment on the first of nextmonth(feb). I said ok, and the the debit went off on the first. Only to find out the they still deducted again on march and then every month since then. Everytime i call they pute through to the cancellations departmant, where i am always put on hold for a good 30 mins of my precious time, then the call just disconnects. This has been happening the last 10 times i called and i am fed up... Please can someone contact me to cancel this nonsens once and for all.... *** nigel. Thanx
